摘要：

AM1 molecular orbital calculations of the reaction path for [2+2] and [2+4] cycloaddition reactions of cyclopentyne lumomer, 2, with ethylene and 1,3-butadiene show concert for the former process and stepwise character for the latter. The results are consistent with Dewar's theory of orbital isomerism in pericyclic reactions.
